For a successful eCommerce site, high-quality images are a must. Customers must have a clear understanding of what they are purchasing in order to make a purchase. However, not all high-resolution photographs are created equal. Some of them may even be hurting your chances of making money online. How? By reducing the speed of loading.
What is image optimization?
Image optimization is the process of reducing the file size of your images as much as possible without sacrificing quality in order to keep page load times as low as possible. It’s also about image optimization. That is, getting your product and decorative images to appear in image search results on Google and other image search engines.
Image optimization refers to making sure your images look great on both desktop and mobile devices. They also don’t stifle web performance.
Image optimization aims to produce high-quality images with the smallest file size possible. There are three main factors at play here:
- File size of the image (JPEG vs. PNG vs. WEBP images)
- Level of compression
- Dimensions of the image
You can reduce image size and improve website performance by striking a balance between the three.
What is the purpose of image optimization?
The largest contributor to overall page size is images, which causes pages to load slowly. According to HTTP Archive, unoptimized images account for 75 per cent of the total weight of a webpage. This can have a negative impact on the performance of your website.

Here’s how to optimize your eCommerce images
Use the appropriate size
Putting the best photos on your website may seem obvious – after all, nothing is too good for your customers, right? However, you can easily overdo it. When we talk about size, we’re referring to both the file size and the screen size. You’ll need to find the right mix of the two so that pages load quickly. Look up the image template information on your eCommerce site to find out what size your image should be. According to Shopify, images with a resolution of 2048 x 2048 pixels look the best. Now it’s time to figure out the best resolution (pixels per square inch).
It’s fairly simple if you use Photoshop. ‘The’ “The “save for web” command allows you to reduce the image file size while maintaining adequate quality. Select the “Color, quality, downsize, and sharpening can all be adjusted using the “optimization” button. You can use free services like PicMonkey, PIXLR, and Canva if you don’t have Photoshop. You should try to keep the image size under 70KB to ensure that it loads quickly. It can be difficult – but making sure you save the file in the correct format will make things easier.
Right image format
JPEG and PNG are the two main file types for saving static images on the web, as you may know. There are a few technical differences between the two, but the most important thing to remember for eCommerce is that JPEGs can be compressed. Use them for product shots – and pretty much anything else – because they’re smaller and load faster. PNGs should only be used for partially transparent images and things like screenshots.
As you might expect, astute software developers have devised a method of further optimizing images using software without sacrificing quality.
Webresizer claims to be able to reduce file sizes by 68 per cent by resizing your images for you online.
TinyPNG lets you do the same thing with up to 20 images at once, thanks to clever technology that removes colours that the human eye can’t see. If you’re using WordPress, WPSmush will compress and resize all of your site’s images for you.
Image alt text
The best way to improve your search engine rankings is to make sure the alt attribute text in the HTML code is filled out. What is the purpose of it? If a browser is unable to load an image, it will fall back on this. Google looks for relevant keywords in alt attributes. This allows you to consider what your customers are looking for when they are looking for the product in question. Your data analytics will provide the answer. If your site visitors are searching for “red leather pumps buckle,” your alt attribute should look like this: img src=”red-leather-pumps-buckle.jpg” alt=”red leather pumps buckle”>. Alternatively, you can simply describe what you see by referring to the file name. You’ll be able to move your site up the rankings once more. As they say, every little bit helps.
Alt text is only required for product images, not for decorative images. You’ll be helping people who rely on web accessibility as well as improving your SERP ranking.
Rule of Thumbnail
Examine your thumbnail. It’s a small space. The same can be said for thumbnail images. However, because you’re likely to have a lot of them on your pages, you’ll want to keep the file size as small as possible to aid page loading. Quality is preferable to tininess. It’s also probably best to avoid using alt attribute text if you don’t want your thumbnails to be indexed by Google.
